The tw200 comes with a low geared transmission. Most of my research shows that those who want better top end speeds need to go from a stock 50 rear to a 47 tooth and in addition go from a stock 14 front to a 15.
That is fine, but can anyone explain why not go to a 45 rear or 43 or 41 etc.....as well as a 16 or 17 front? Can anyone explain what happens as you keep going and why the 47/15 seems to be the best improvment?
Getting correct chain tension, perhaps?
